FAQ

This S488 is intended for universal performance builds that require an 88mm compressor, T6 twin-scroll 1-32 housing, 96/88mm turbine and race cover. It is not an engine-specific direct replacement.

The S488 1-25 T4 uses a T4 flange and a 1-25 A/R housing. This page uses the larger T6 flange and a 1-32 A/R housing. Match both the flange and housing ratio to the build.

No. 171702 identifies an S475/96/1-32 configuration and is shown only as a related replacement reference. It is not a direct OE for this S488 configuration.

Why 88mm + T6 1.32

  • 88mm billet wheel — larger compressor configuration within the S400 performance family.
  • T6 twin scroll — matches manifolds designed for the T6 flange.
  • 1.32 A/R — match the housing ratio to the airflow and response requirements of the build.
  • Race cover — compressor cover profile for the intended intake plumbing.

Cross Reference Numbers

No direct OE or same-part interchange number has been verified for this S488 configuration.

Related reference: 171702 — S475/96/1.32 replacement reference only, not a direct OE for this S488 configuration.

Installation and Care

  • Find out why the old turbo failed before installing the new one. Oil starvation or contaminated oil will destroy the replacement the same way.
  • Change the engine oil and filter. Flush or replace the oil feed line.
  • Verify the T6 flange and 1.32 A/R housing against the build before installation.
  • Prime the turbo with clean oil and check the oil drain path for restrictions before startup.
